这是什么?

@fluffy-spoon/name-of 这使得在运行时间获得财产名称成为可能,即使该类型在运行时间不存在. 把它当作 nameof c# 中的关键词, 但用于 TypeScript .

安装

npm install @fluffy-spoon/name-of

使用量

import { getPropertyName, getDeepPropertyName } from '@fluffy-spoon/name-of';

interface SomeType {
  foo: boolean;

  someNestedObject: {
      bar: string;
  }
}

console.log(getPropertyName<SomeType>(x => x.foo)); //prints "foo"
console.log(getPropertyName<SomeType>(x => x.someNestedObject)); //prints "someNestedObject"
console.log(getPropertyName<SomeType>(x => x.someNestedObject.bar)); //prints "bar"

console.log(getDeepPropertyName<SomeType>(x => x.foo)); //prints "foo"
console.log(getDeepPropertyName<SomeType>(x => x.someNestedObject)); //prints "someNestedObject"
console.log(getDeepPropertyName<SomeType>(x => x.someNestedObject.bar)); //prints "someNestedObject.bar"
